" inside attribute in xslt

Question

hi i am trying to write a regular expression inside an xslt but i have a problem with the " sign. i closes the attribute. and \" dosnt seem to work like it works in aspx pages

here is my code:

<xsl:if test="@text = 'yes'">
  <asp:RegularExpressionValidator runat="server" ControlToValidate="{@name}" 
   ValidationExpression="^[\w '%+*.!=/\\\[\]\{\}\?\,\(\)-]+$"
   ErrorMessage=" " Display="Dynamic">
      <span class="red_star">*</span>
  </asp:RegularExpressionValidator>
</xsl:if>

how can i add the " sign to the regular expression? so it will be like this:

ValidationExpression="^[\w '%+*.!=/\[]{}\?\,()\"-]+$"

thank you

Answer 1

You should be able to express " with the xml entity "

Answer 2

Since you're generating another XML document (or aspx, or HTML, for that matter), I believe you need a little more encoding. For the example, suppose you want attribute to be abc"edf:

attr="abc"edf", as suggested, will cause the XSL engine to see the text as attr="abc"edf". In this case, the XSL is valid, but the generated document isn't!.

What you probably need here is:

attr="abc"edf"

Here, the XSL engine sees and generates attr="abc"edf" - that is, you want " to be part of the output, not the input.

_{(As an alernative, you might get away with single quotes: attr='abc"edf' - this wouldn't help here though, because you also have a single quote in your string...)}
